1.與激光測距技術(shù)相比，有簡單和經(jīng)濟(jì)的優(yōu)點(diǎn);
2.超聲技術(shù)一般不需要運(yùn)動(dòng)部件，所以在安裝和維護(hù)上又相應(yīng)比較方便;
3.超聲波物位計(jì)不僅能定點(diǎn)和連續(xù)測位，而且能方便的提供遙測或遙控所需的信號;
4.超聲波物位計(jì)與放射性測位技術(shù)相比，不需要防護(hù)。
技術(shù)特點(diǎn)
1.具有強(qiáng)勁發(fā)射力的換能器，表面可自清潔，利用更新的換能器結(jié)構(gòu)和制造工藝，顯著提*了換能器的工作**。
2.微處理器程序控制、智能信號處理技術(shù)，可實(shí)現(xiàn)多種典型工況軟件處理模式，使物位計(jì)能適應(yīng)固體、液體、粉塵等復(fù)雜工況。
3.紅外線遙控編程調(diào)節(jié)，操作簡單可靠，并帶有液晶現(xiàn)場顯示。
4.非接觸式連續(xù)測量，減少維護(hù);
5.可用于測量物位、空間、距離，也可對標(biāo)準(zhǔn)或特別開關(guān)的液罐進(jìn)行自動(dòng)液位-體積轉(zhuǎn)換;
6.帶背光的液晶顯示器，可按標(biāo)準(zhǔn)工程單位進(jìn)行顯示。
